AND OBIID KING AND EZRA KING,

OF SALEM, IOYVA.

HAND-LOO1VL Specification of Letters Patent No. 9,388, dated November 9,1852.

To all whom, it may concern;

Be it known that I, STEPHEN C. MENDEN- HALL, of Richmond, in the countyof Wayne and State of Indiana, and Onnn KING and EZRA KING, of Salem, inthe county of Henry and State of Iowa, have invented certain new anduseful Improvements in Looms; and we do hereby declare that thefollowing is a full, clear, and exact description thereof, referencebeing had to the accompanying drawings, forming a part of thisspecification.

Our invention consists first in effecting a movement of any number ofheddles and varying the number of the same by a motion derived from thelay, so as toproduce fabrics of two or more leaves with the same loomwithout the use of cams and without removing any part of the machinery;and second, in effecting a throwing of the shuttle by an inclined planeaction, which operates independently of that for shedding the web.

Of said drawings Figure 1 is a transverse vertical section, showing thetreadle stick or finger depressing one of the treadles to the fullestextent; Fig. 2 a view of the mechanism for effecting a movement of theheddles, detached from the lay and breast beam; Fig. 3 a detached viewof finger shaft and finger with the springs for recoiling the same; Fig.4 a view of the 'mechanism for effecting the throwing of the shut tle;and Fig. 5 a detached view of picker staff, showing the double inclinedplanes upon its end.

Similar parts in each of these figures are designated by the sameletters of reference.

a, are the beams, b the stanchions connected together by the breast beamand other cross ties, which are constructed of such form and size as aresuitable to support and sustain the moving portions of the machinery.

A are the treadles (which can be varied to any desired number as we canoperate two or more of them at pleasure and can produce with the sameloom fabrics of any number of leaves) swung from behind instead of fromthe breast beam as usual in hand looms from the arms B projecting downfrom the treadle tie C.

D are arms secured to the top of the treadles which serve as guides andabutments for the finger E to act against.

her when the lay is again on The mechanism by which we are enabled tooperate any number of heddles and Vary the number of the same atpleasure with the same loom without the use of cams and without removingany part of the machinery consists and may be described as fol lows: Fis the finger shaft which is constructed square at one end for part ofits length the remaining part being a round shaft, cut through itssquare end is a mortise through which mortise pass and are secured aseries of pins H which correspond in number to the treadles andserve asabutments for the wherve K to act against. On the top side of saidsquare end are provided a series of notches I which are the samedistance apart as the pins H but are less in number than the treadles,and suitably suspended 011 a fulcrum in the beam of the lay is a pawl Jwhich falls into said notches so as to prevent the shaft F from movingin one direction while it is kept from moving in the opposite directionby a spring G. iittached to the square end of said shaft is an inclinedplane 0. E is the treadle stick or finger which moves freely on theround part of said shaft but is kept close against the shoulder thereofby a spring G which spring also answers the purpose of causing saidfinger to act gradually upon the abutnients D and assume a positionagain when the lay is on its backward movement to operate against theabutment in the same manmovement.

Cut through the beam of the lay is a mortise into which is secufed theguide boards M M and it is provided with an in clined plane N. The guideboards are for the purpose of guiding the wherve K into the mortise ofthe finger shaft and the inclined plane N by its action upon the end ofsaid wherve causes a movement of the finger and shaft at each backwardmovement of the lay in the following manner: 0n the backward movement ofthe lay, the wherve K, which is hinged to the underside of thebreastbeam and provided with a spring L which keeps it close against theside of the board M, is guided by said boards so as to enter the mortisein said finger shaft and by acting against the inclined plane or by theaction of the inclined plane upon its end causes it to force the fingershaft to slide the distance of one of the its forward notches I or inposition to operate upon the next treadle, thus at each backward movement of the lay the shaft F is moved one notch by the action of thewherve as described, in which position it is retained by the pawl Juntil the finger has operated a treadle and the wherve adjusts it againready to operate the next treadle. After the number of treadles toproduce the number of sheds required have been successively operated inthis manner the inclined plane 0, causes the wherve K to slide up overit and under the pawl J which releases said shaft F and allows it torecoil to the starting point ready to repeat the same sheds. With thisarrangement for effecting a movement of the heddles, it will be seenthat to vary the number of heddles to produce any number of sheds of theweb it is only necessary to prescribe the limit to which the fin gershaft shall slide or recoil in the lay, and that said shaft can beadjusted so as to operate two or any number of treadles, by simplyinserting a pin through holes pro vided on the lay beam at suitabledistances apart for that purpose as represented in Fig. 2, or a bit ofwood placed in the mortise in which the shaft slides so as to check itwill answer the same purpose.

In the action of the treadle stick or finger on the treadles, there isthis feature of difference between our arrangement and all other handlooms-z Our treadles are swung from behind instead of from the front sothat the finger acts upon them at nearly a right angle, and the leveragecan be increased to any extent, whereas in other looms when the treadlesare swung from the breast beam, the finger acts at a greater angle andconsequently proportionally diminishes its power to effect a movement ofthe heddles.

Our simple device for effecting the throwing of the shuttle back andforth when the web is shed b mechanism independent of that for shed ingthe web operates upon the principle of the inclined plane. The

picker staff is pr vided with inclined planes near its fulcrum which areso arranged with and operated upon by hooks on the breast beam as toproduce a very regular and perfect back and forth motion to the shuttlesaid hooks being self acting.

Q, is the picker staff formed with inclined planes Q, on each side ofits fulcrum. This peculiar construction of the picker staff incombination with the hooks R, R, and spring T, have the efi'ect to raisesaid hooks alternately clear of the shoulders s, s, on said picker staffproducing a catching or impinging of said hooks against the shoulders ofsaid picker staff on the forward movement of the lay. Said hooks arehinged to the breast beam and has a spring T be tween them so that, theyshall have both lateral and vertical play; when the picker staff is inthe position represented in the drawing one hook is acting against oneof its shoulders a, while the other hook which is held close against theround part of said picker staff by the action of the spring T, and isforced to slide up the inclined plane Q thus clearing the hooks of theshoulders of said picker staff alternately and effecting a sure throwingof the shuttle.

Having thus fully described our invention, what we do claim and desireto secure by Letters Patent is 1. The combination of wherve K operatedby lay, inclined plane 0 and its guides M M, and adjustable pin W, ortheir equivalents B combined and operating as described, so that, we canoperate and vary the number of heddles substantially as and for thepurpose set forth.

2. Ne are aware that the picker staff has been operated by hooksalternately raised from the shoulders on the picker staff by pins on avibrating slide operated by grooves in the treadle camthis we do notclaim but we do claim the combination of the inclined plane, Q, onpicker staff, spring T, and hooks R, R, for the purpose of lifting thehooks in the manner and for the purpose specified.

In testimony whereof we have hereunto signed our names before twosubscribing witnesses.
